Michael,
I believe OSSIM http://www.ossim.org/tiki-read_article.php?articleId=10
uses wxWindows, or at least initially . You may want to contact the OSSIM
developers about their experiences with it. Glancing at the website, it
seems that their method allows for muliple gui development options. Now
that qt and gtk are available for windows, you don't hear as much about
wxwindows.

[GRASSGUI] Re: [GRASS5] GRASS GUI -
platforms
Running 'natively'--or as natively as possible--will make it MUCH easier
for
more people to who want to use GRASS to do so. It will also be easier to
learn more of the complexities of GIS and spatial analysis if they can
install it easily and simply run it easily.
TclTk is somewhat easy to work with because it doesn't have to be compiled.
HOWEVER, I now have 3 versions of TclTk on my Mac--the one that comes from
Apple (that GRASS does not use), the X11 version that I prefer, and the
aqua
version that Lorenzo Moretti has used to give GRASS an optionally more
Mac-like appearance. Windows users need 2 versions of TclTk because the
version that comes with Cygwin doesn't work with GRASS. (Oh yeah and they
need Cygwin too). Some Linux users need version 8.3 in addition to the
version 8.4 that comes with their system. This is a mess. If we were to go
with TclTk, this would have to be cleaned up. But I don't know if it's
possible.
I also have heard that QT is making an open source version available for
Windows, but don't know the status of that. This is a pretty critical
issue,
but perhaps solved already.
As someone else mentioned, GIMP works pretty transparently on my Mac, even
though it runs under X11. So does Inkscape (also GTK I think). Apple gives
away a Mac-specific version of X11, so this is not a problem AFAICT. I've
seen GIMP run on Windows XP and it appears to run natively (ie., no need
for
Cygwin or x11 emulation). GTK seems to be widely standard on most Linux
systems too.
Someone also mentioned wxwindows as a platform candidate. I haven't heard
of
this. Has anyone else?
Michael
